Two new non-glycosidic iridoids from Sambucus ebulus

Two new ‘Valeriana-type’ non-glycosidic iridoids were isolated from the aerial parts (leaves and young branches) of Sambucus ebulus L., a perennial herbaceous species widespread in Europe. The structures were elucidated, by spectroscopic means, as 7-O-acetylpatrinoside aglycone (1) and 10-O-acetylpatrinoside aglycone (2).
